DPC Latency is driving me insane! I get incredible DPC spikes that mess up my sound. I am running the DPC Latency check program and at times will get solid red bars all the way up to the top! I have tried many things without success. These are the things I have tried that have NOT worked:

Disabling devices
Reinstalling Windows XP
Disabling ACPI
Turning off dynamic switching
Running Ubuntu instead of Windows

My PC is an Acer Aspire 5720 laptop with a 1.60 ghz dual core processer with 1.5 gb ram running Windows XP service pack 3.

Thanks for any help you can give me.

You have a sound card by any chance? Seems like its a streaming Audio and Video checking tool DPC I just ran a problem that I Googled and I found my machine ran at 100 Us So.. I'm guessing it may be an issue with the sound card? Just a guess.
